LG today announced two new additions to its premium Android smartphone link, the F Series. The LG Optimus F5 and the LG Optimus F7 will begin shipping in Q2 this year. Here's more info on these upcoming Android smartphone devices from LG:

The Optimus F5 is a 4G LTE smartphone with a 4.3-inch IPS display running on a 1.2GHz Dual-Core processor and largest-in-class 2,150mAh battery while the Optimus F7 offers a 4.7-inch True HD IPS display and a 1.5GHz Dual-Core processor powered by a large capacity 2,540mAh battery for long lasting performance. Both devices will be available with the latest Android Jelly Bean 4.1.2 OS and will include advanced UX features such as the upgraded QSlide and Live Zooming, previously only available in LG's premium devices.

The upgraded QSlide allows users to open two apps at the same time, both in full screen mode. Users can change the size, position and transparency of QSlide apps according to their preferences. Functions now compatible with QSlide include video, browser, memo, calendar and calculator. Live Zooming, previously only seen in the Optimus G, is now standard in the Optimus F5 and Optimus F7. Live Zooming allows the user to zoom into a specific area while watching a video. Additional features included in both Optimus F Series devices are QuickMemo, QTranslator, Video Wiz, Safety Care and much more.
